Simulation stopps

bmandt

Dear all,
I try to simulate a moving tank in 2d.
After starting the simulation it stops with the error:

[Initialising simulation (0zb43098) 18-02-2014 10:14:33]
PART PartTime TotalSteps Steps Time/Seg Finish time
========= ============ ============ ======= ========= ===================
Exception (JSphGpuSingle::Interaction_Forces)
Text: Failed in reduction of viscdt. (CUDA error: unspecified launch failure).



*** Exception (JSphGpuSingle::Interaction_Forces)
Text: Failed in reduction of viscdt.

Do anybody know what the reason is. I also tried a 3D-case with the same result.

Last Nvidia-Driver is installed.

Thank you for your support.

Best regards,

Benjamin

I try to simulate this case too and get error.
As one of developers say (Stephen Longshaw) :

"Simply calculate a set of acceleration values equivalent to the motion
you wish to impart, keep your boundaries static and include the
acceleration data (you will only need 1 file) as per the example case
provided with DualSPHysics 3.0."

Dear Benjamin,
I am interested in this case.
Send please your results if you will handle problem well.
Best regards,

Hello, in order to diagnose the problem with this case it would be useful if you could send through the xml of the case causing the error.

There's a possibility that you have uncovered a bug in dualsphysics 3, so it would be good to see. If you are able please send the case through to me at my listed email address.

The advice i gave to Sergey and that he has reiterated above, is the advice i would give to anybody trying to simulate a moving tank, in fact the variable acceleration functionality was introduced originally to exactly solve this problem.

Best regards.

What GPU card are you using??

Hi,

I also meet the same problem when I debugg this code. Who can tell me how to settle it?
